Maths In Java

I'm trying to create a simple mathematical code using Javascript. What i want to do is have a text box which people can insert a number into, then press calculate and get a result.

e.g Hidden price in code of 1.99, on webpage user says i would like 2, then they press calculate and a total appears at the bottom of the screen.

Any ideas would be appreciated, i would prefer not to use cgi-scripts.

Cheers

Steve

Thanks, i'm a bit nearer to my target now, basically i have an order form and wish to have a total price at the bottom of the page that updates when they put their quantities in.

Cheers
